摘要

As a nearly US8 billion business in the U.S.alone,according to 2000 data from the U.S.Department of Agriculture,organic fruits and vegetables have moved rapidly from a fringe business at the local food co-op to a mainstream supermarket staple.A key reason consumers buy organic is to avoid pesticide residues,but a small study suggests that organic produce may not be quite as clean as shoppers expect.
